Every February we get the same calls: a burst hose bib, a ceiling stain under an ice dam, a heat bill that doubled. Almost all of them trace back to something that takes twenty minutes in October. Winter in Northern Illinois isn't sneaky — it shows up every year, on schedule, with a grudge. Here's the checklist we run on our own homes — and on our customers' homes as a one-visit winterization service.
The single most expensive skip on this list. A hose left attached traps water in the faucet, the first hard freeze expands it, and the pipe splits inside your wall — you find out in spring when the wall is wet and the insurance adjuster is learning your first name. Disconnect hoses, shut the interior valve if you have one, and drain the bib. Twenty minutes, zero regrets.
Clogged gutters anchor ice dams and dump meltwater next to your foundation. Clean them in late fall after the oaks finish — and oaks are notorious procrastinators, dropping into December — not early October when they'll just refill. Downspouts should carry water several feet from the house. (Full detail in our ice dam guide.)
Walk the house on a windy day with the back of your hand near window edges, door sweeps, and outlets on exterior walls. It's like a scavenger hunt where every find saves you money. Cracked caulk and flattened weatherstripping are cheap fixes that pay for themselves in one heating season — and they're a core part of our window sealing work.
Fresh filter in, supply vents unblocked, and ceiling fans reversed to clockwise so they push warm air back down. Free comfort — the switch is on the fan body, and yes, that's what it's for.
Attic hatches, recessed lights, and bath fans leak warm air into the attic — which is exactly what melts roof snow into ice dams. Weatherstrip the hatch, and if your bath fan vents into the attic instead of outside, fix that before winter, not after the mold.
Swap screens for storm panels, seat storm windows, and adjust door thresholds so exterior doors actually compress their weatherstripping. A door that shuts with a soft “thunk” is a door that's sealing; a door that rattles is a door mailing your heat outside.
October is the sweet spot — after the summer heat, before the first hard freeze. The hose bibs and drafts can't wait past the first freeze; the gutters wait for leaf drop. That's why our service visit handles the urgent items early and times the gutters right.
They're more forgiving, not invincible — and a hose left attached defeats the frost-free design entirely. Disconnect the hose no matter what kind of bib you have.
The attic checks. Nobody wants to stick their head up there — which is fair, it's itchy — but that's where the heat (and the money) leaves. It's also the root cause of most ice dams.
Yes — newer homes seal better but still have hoses, filters, gutters, and fans. And builder-grade weatherstripping often fails faster than the good stuff. Newer just means fewer surprises, not zero.
Our winterization service covers this whole list — checked, fixed, and documented with photos — in a single visit, with small repairs handled on the spot. And if you'd rather never think about this list again, it's built into our Home Care Plan as the fall visit. October and November dates go fast once the first frost hits.
